In React, handling onClick events can be done in two common ways: using a direct call or an arrow function. Understanding the differences between these approaches can help you write cleaner and more efficient code.
Approach 1: Direct Call
<button onClick={handleClick}>Click Me</button>
Props and Con:
Execution: The function is passed as a reference and is only called when the event occurs.
Performance: More efficient as it does not create a new function on every render.
Use Case: Ideal for simple event handlers that do not require additional arguments.
Approach 2: Arrow Function:
<button onClick={() => handleClick()}>Click Me</button>
Execution: Creates a new function on every render, which then calls the specified function.
Performance: Less efficient due to the creation of a new function each time the component re-renders.
Use Case: Useful when you need to pass arguments to the event handler or bind the function to a specific context.
In summary, while direct calls are generally more performant, arrow functions offer flexibility in passing arguments and binding context. Choosing the right approach depends on the specific needs of your application
